My RE originally said I would be on progesterone until 12 weeks. I had an ultrasound at 8 weeks and was told to go every other day with progesterone and then I was good to stop. I'm a little bit nervous. I'll stop early next week or so but will be in Europe at the time so if anything is wrong, there's nothing I'll be able to do. I see my regular ob/gyn on Friday but even if she checked my progesterone levels, I won't get the results back until I'm away.
